Is it true that when you quit your job your employer is required to continue your Health Care for 30 days?

I live in NY and am qutting my job, my last day is next Friday. I heard that your employer is required to provide you with health care insurance for 30 days after the date you quit, is this true?

Cobra requires that the employer make health insurance available to you for 18 months, but it's at your expense.

There is no law that requires insurance be continued at the employer's expense. There might be a union contract, but not otherwise.
